Edition 1

1.Introduction

This article provides instructions for setting up, installing, using and maintaining the ST2042 Door Central.

2.Overview

Following is an overview of the PCB board for the different models of ST2042

2.1 ST2042 PoE+

2.2 Connections

3 Status LED indicators

The ST2042 PCB board is equipped with three status LED indicators that provide
important information about the device status.

• First indicator marked ACT on the board flashes when firmware is successfuly running. This indicator should blink approximately every five seconds. If ACT does not blink, it may indicate an issue with the ST2042 or its hardware.
• Second indicator is marked PWR it remains steady on when ST2042 device is powered and functioning correctly. This LED reinsure that device have a steady power supply. Flickering on this LED is most likely a result of lack of sufficient power supply or PoE+ delivery.
• Third indicator is WDT and is a watchdog timer that is the system overwatch. This flashing once per second when the watchdog is operating.

4 Power supply

When using the ST2042 PoE+, the current consumption will depend on the voltage used to power the device. If the ST2042 PoE+ is powered using a 24-volt supply, it will consume approximately 150 milliamperes (mA) of current. Conversely, if a 12-volt supply is used, the ST2042 PoE+ will require approximately 300 mA of current.

4.1 AC/DC External power supply

The J12 input is a connection point for an external power source, which can be either an AC or DC power supply. This input allows the ST2042 to be powered by an external power supply.

The acceptable range for input voltage is between 12-24V.
This means that any voltages within this range can be safely used to power the device.

NOTE: It is important to note that using a voltage outside of this range may cause damage to the device and should be avoided. Additionally, it is recommended to use a power supply that is balanced and ripple-free, with a minimum capacity of 2 amperes. Take care to choose a power supply that is suited for fine electronic circuitry

4.2 PoE+

The ST2042 PoE+ control board can be efficiently powered using the PoE+
(Power over Ethernet) IEEE 802.3at standard. This allows for the
simultaneous transmission of both data and electrical power over a single
Ethernet cable, simplifying the installation process and reducing the need
for additional power cables or outlets.

NOTE: Under the IEEE 802.3at PoE+ standard, each PoE+ enabled port can
deliver up to 30 watts of power.

4.3 Strapping pin

ST2042 has 2 strapping pin both this pins is to adjust output power.

J3 is used to adjusting the power output for the J2 Lock output.

J8 is used to adjust the power output for the card reader or other OSDP
devices connected to the door controller.

Clarification:

• By setting strapping pin to 24V you redirect input power to the lock. So in case you feed the device with more than 24V, that will be fed to the lock without regulation. 24V means feed input voltage to the lock.
• If system is powered by a 12V power supply strapping pin should be set to 24V output as 24V means output the input power.
• 12V strapping can only be used when using 17V or higher input voltage.

5 Outputs

5.1 J2 - Lock Output

The pins on the "Lock-relay" are identified with the labels "+(nc) | - | +(no)".
In practical terms, if you have a fail-secure electronic lock setup, you would
need to connect the "+" wire to the right pin “+(no)”. Conversely, if you
have a fail-safe configuration, the "+" wire should be connected to the left
pin “+(nc)”.

NOTE: It is important to note that the correct wiring configuration depends
on the type of electronic lock used. A fail-secure configuration locks the
door in the event of a power failure, while a fail-safe configuration unlocks
the door in the same situation. Therefore, it is crucial to identify the correct
wiring configuration for the specific lock used to ensure proper operation
and security.

5.2 J7 - Relay Output

The J7 - Relay Output, is a potential-free relay that can be connected to one door environment on the same way as the lock output. It can also be connected to a own door environment to with own readers separately from the door environment controlling the lock output.

5.3 J14 - Bypass switch

The J14 - Bypass Switch is a dedicated trigger relay switch designed for
controlling a single alarm zone. This switch allows you to bypass an external
alarm for the specified zone.

Please be aware that the J14 - Bypass Switch is designed to control only one
zone at a time. To manage multiple zones or customize zone controls,
consult the appropriate sections in the alarm system's user manual.
Configuration of these functions must be performed within the alarm system
itself to ensure proper operation and security.

6 Inputs

6.1 J4 - LED +/-

The J4 input serves as a confirmation point for the activation or deactivation
of the alarm system. The LED input must be connected when using an external
alarm system. The input is designed to accept a voltage range of 5-12V DC,
ensuring compatibility with various alarm system configurations.

6.2 J5 – Open button

The J5 port, also known as the Open button input, is designed to trigger
an output. As standard it is connected to the lock output, but this can be configured
in the cloud where you can connect the input to several outputs.

The open button has two different modes Normal mode or Bistable

In normal mode button activate the connected outputs and the outputs will be released when unlock time or door is opened.

In bistable mode button activate the connected outputs and hold them in active state until button is released + open time.

NOTE: It is important to note that triggering the J5 port will cause an
immediate and simultaneous activation of the J7 and J2 ports. Therefore, it
is recommended to use this feature carefully and with proper consideration
of the potential consequences

6.3 J1 - Door sensor

The Door sensor input is used to monitor the status of the door sensor.
If the input is connected to a door environment, the door open time will be cut of when the door is opened and the lock will be locked.

If a door sensor is connected to a door environment it is also possible to use it as door alarm. In this case the card reader will be able to, by sounding the buzzer, inform about an open door. It can also be reported by email.

Note: It is also possible to change J1's function in the Cloud so that it can be used as an Open button.

You can then set up two separate door environments, each with its own dedicated card readers and Open button.

7 Interfaces

7.1 OSDP interface

The ST2042 is equipped with a OSDP communication interface, this is used to connect a OSDP slave
(Card reader or Lock) to the controller.

Card reader is connected to the door controller by use the CON3 power out and CON4 OSDP output.

Voltage to the Card reader is controlled with the J8 strapping pin

Note: No joints/splices are allowed between the Door Controller and the card reader.

• Add the MAC address of the device to the end customer’s Cloud tenant. This will ensure that the access system is properly integrated and is able to communicate with the designated device.

8.2 Cabling

Prior to installing the ST2042 Door controller, it is crucial to ensure that
all necessary cables are properly installed in the door location

8.2.1 Ethernet cable

The first and most important cable is the network cable this is required to be at least CAT6 and connect the door controller with the PoE+ enabled switch. This cable provides power and Ethernet connectivity for two way communication between the door controller and the Cloud. To ensure proper installation, it is recommended to test the CAT 6 cable with at network tester to confirm it is working correctly.

8.2.2 Standard wiring

In addition to the Ethernet cable, standard wiring is required to connect the electronic lock, exit button, and other related components to the door controller. It is important to install these cables securely to prevent any complications or errors during the installation process.

Note: When using an external power supply for the door controller, it’s advisable to verify that the incoming power is within the recommended range. By doing so, you can prevent potential power related issues and ensure the device operates correctly.

8.2.3 Tools, cables and plugs

Being well-prepared with the necessary equipment can facilitate a smooth
and efficient setup, reducing the likelihood of encountering issues or delays.
Some of the tools you may want to have on hand for a seamless installation

includes:

• A high-quality RJ45 termination tool is indispensable for a successful installation.
This tool guarantees a secure and accurate termination of the CAT6 cable to the RJ45 plug, which is vital for establishing a stable and reliable connection between the door controller and the PoE+ enabled switch.

• An RJ45 network cable tester is essential for evaluating the CAT6 cable after termination. This instrument helps verify that the cable has been correctly terminated and is functioning as intended, ensuring the integrity of the connection.

Note: It's essential to use high-quality RJ45 plugs for secure and accurate terminations, as this contributes to stable and reliable connections. Be sure to use short plugs to maintain optimal performance and connectivity.

• CAT6 cable, either shielded or unshielded, is required for the connection between the ST2042 and the PoE+ enabled switch. The choice of shielded or unshielded cable depends on the specific installation environment and requirements.

8.3 Physical installation

NOTE: It is crucial to verify that all cables are installed properly and
securely to prevent any potential complications or errors during the installation process. 
It is recommended to visually inspect all cables and use a network tester to confirm 
that the cables are in good working condition before proceeding with the installation. 
This will help to prevent any potential issues that may arise due to faulty or improperly 
installed cables.

IMPORTANT: Always remove power to the door controller before connecting 
devices or accessories to it

8.3.1 Placement

One common location for mounting the door controller is above the door, as this is
typically where most of the electronic lock, exit button, and door operator connection are located.

8.4 Connecting lock

8.4.1 Fail Secure

To configure the ST2042 for fail secure mode, connect the positive (“+”) wire
to the right pin “+(no)” of the J2 Lock Output and the negative (“-“) wire to
the middle pin of the J2 Lock Output, as shown below. Take care to set the
strapping pin to the correct voltage of the lock.

Note: When powering the door controller with 12V the maximum output of the 
lock power is 12V. Always set J3 strapping pin to 24V (unregulated) when using system
on 12V, reason is that door the controller uses a stepdown controller to create 12V and it needs
at least 17V to work properly.

8.4.2 Fail safe

To configure the ST2042 for fail-safe operation, connect the positive (+) wire
to the left pin “+(nc)” on J2 Lock Output and the negative (-) wire to the
middle pin (-) of J2 Lock Output. This wiring configuration ensures that the
door will remain unlocked in the event of a power failure, allowing for safe
exit from the building.

Note: When powering the door controller with 12V the maximum output of the 
lock power is 12V. Always set J3 strapping pin to 24V (unregulated) when using system
on 12V, reason is that door controller uses a stepdown controller to create 12V and it need 
at least 17V to work properly.

NOTE: If electronic locks other than Steplock are being used, it is
recommended to install a protection diode (e.g. 1n4004) between the
electronic lock and the output.

8.5 Connecting Open button

Connecting the exit/open button to the door controller is a simple process. Connect them to the J5 connector If the button needs to be supplied with power, extract power from CON3.

NOTE: If you plan to use several card readers and a open button that need power supply, it is crucial to plan  your power consumption carefully to ensure that you have enough power available for all the devices you need to use.

8.6 Door sensor

Connecting the door sensor to the door controller is a simple task. Connect the to wires to the J1 door sensor input as picture below.

8.7 Card reader

The door controller features an interface for OSDP devices, the OSDP interface is located at CON4 and the Power is located at CON3, from these two connectors it is 4 cables running
to the card reader.

The door controller can handle up to 4 individual card readers on a ST2042 door controller.

Note:

• It is important to address each card reader to an unique address with the address switch on the reader. If you wish to use other brands of reader than Steplock, please advise the readers manual for instructions how to address that specific OSDP device.
• Always advice the card reader manual before connecting the power on CON3, the power is adjusted by selecting between 12V or 24V out
• 24V on the strapping pin means unregulated power is connected to the output.
• 12V on strapping pin means regulated power this give 12V out if you power device with at least 17V.
• If system is powered with 12V the strapping pin should be set to 24V aka (unregulated). This will give 12V output.

8.8 Intruder alarm

The door controller can be connected as a Master to a alarm system.
When door controller is connected to a alarm system it can handle
arm / disarm and automatic arming.

You connect door controller by wiring one bypass input to the J14 Bypass switch
and a output status to J4 input. J4 can receive 5-12V DC as status.
